To all whom it may concern.-

Be it known that I, DANIEL OBRIEmof Brooklyn, in the county of Kings andState of New York, have invented an Improvementin Dumping-Oars, of whichthe following is a specification:

The object of this invention is to simplify the construction of thedumping-cars used in conveying earth, gravel, &c., from. one place toanother, thereby avoiding the constant repairs, detention, and expensesconsequent upon the use of the ordinary dumping'cars.

In the drawing, Figure l is a vertical section transversely of the car.Fig. 2 is a sectional elevation of the same at the line a: w and Fig. 3is a plan view of the latch-lever detached.

The oblong frame a rests upon the journalboxes or bearings b of theaxles 0. d are the car-wheels of ordinary character. The lower parts bofthe boxes or bearin gs are attached by bolts passing through slotsmade transversely of the box, (see inverted plan, Fig. 4,) so that byslackening these bolts the box 6 can he slipped laterally from beneaththe journal sufficiently for theinsertion of oil' and cottonwaste intothe cavity provided in such box, after which the box is slipped back andheld to its place. This avoids the risk of loosening nuts and boltswhich now exists. The drawbeam d of the car runs through the frame a,

and its ends form the buffers of the cars. The coupling-chains e andhooks are made to hang below the buffers, and there is a clevis, f, atthe end of each chain that passes above and below the stationary tongueg, and through these the coupling-pin it passes. By this constructionthe coupling-chain hangs below, and does not get between the buffers,and does not become injured, and the chains can be hooked together, moreor less, afterthe cars have been run together, and the chains are freeto draw with the clevis into any desired position. Upon the bearing-beamh the central sill k of the car-rests, and the two are hinged togetherat 2.

The car is of usual size and construction, except as hereafter named.The bottom m, ends n, and swinging side 0 are constructed upon theordinary plan, except that it is preferable to have the pivots 4 uponwhich the side 0 swings higher up than heretoforeusual, to allow thesame to openfarther, and the side pieces 5 are extended up above thepivots. -When theearth is being dumped from this car down an embankmentthe side 0 will generally swing open sufficiently by its own weight forthe delivery of the earth but, in order to open the same wider, to clearthe earth when dumped upon a level, I attach to the upper end of theside pieces 5 the chain or rope 6 passing around the pulleys 7 and 8,and attached to the frame a, so that whenthe car is dumped into theposition; shown by dotted lines, Fig. 1, the rope or chain 6 will havedrawn the upper end of the side piece 5 inward and swing the side awayfrom the pile of earth dumped from the car.

In order to latch the swinging side 0 of the car, I make use of a lever,1", upon theunder side of the car-box, pivoted at 9, and at one endthere is a hook, 10, to catch the projecting metal plate 11 upon the singing side to, so as to hold the same, and I make use of this samelever r to lock the car-box, so that it cannot tip. To effect this Imake anotch in the bearing-sill s to give space for the lever r, and atone side of this notch I bolt a plate, 14, to the bearing-bar, the samehaving a hooked end,

beneath which the locking-lever 1" passes when it is moved to lock theswinging side of the box, thereby securing the car-box from tipping, andholding the swinging side by one movement of the lever r. This lever ris guided by a plate, a, upon the under side of the car-sill v, andthere is a swinging. hook, to, at this side of the car that serves tolock the lever r, and said book may be arranged to hold the lever 1" ineither position to which it may be moved, and hold it when the car isfull, or hold it out of the way while the car is being dumped orreplaced.

I make use of a lever-brake, w, pivoted at l6, and moving in a slot atone end of the frame a, so that the brake can be applied by pressurefrom the foot. There is a hanging hook, 17, (shown detachedin Fig. 5,)that can be passed under the lever to hold it up out of the way, orover-the lever to hold it and the brake down. By this construction theattendant is able to brake up one car after another with ease andrapidity.

In Fig. 6 the brake a: is shown as single, and in Fig. 2 it isrepresented as acting on the two brake levers x 00 so as to'apply thepower to both the oar-wheels. These brakes are'not in the way of the caras it is tipped.

I claim as my inventionv l. The draw-beam d, forming also the buffers,and the stationary tongue g, in combina tion with the coupling-pin h,elevice f, and chain 6, substantially as set forth.

2. The boxof the ear, made with the swinging side 0, pivots 4, and sidepieces 5, in combination with the rope or chain 6, and pulleys,substantially as and for the purposes set forth.

3. The lever r, pivoted at 9, the hook 10, and catch-plate 11, on theswinging side 0, in combination with the hooked plate 14, substantiall yas set forth.

4.. Thehook w, in combination with the lever 4*, hooks 10 and11,'car-box, and swinging side 0, as and for the purposes set forth.

5. The brake-lever w, placed at the side of the frame a, opposite tothat at which the box is dumped, and moving near its end in a slot inthe frame a, in combination with the hook 17, for holding thebrake-lever either up or down, as set forth.

6. The brake a: and brake-levers .00 m arranged as shown, so that thebrake-levers 00 0: are operated simultaneously by the brake a2, and theparts are not in the way of the car as it is dumped, as set forth.

Signed by me this 6th day of September A. D. 1876.
